Hi,
Here are the main differences I have found between the ONF Bundle extension
(EXT-230) to OF 1.3 and the OF Bundle specified in OF 1.5.1:
* No OFPC_BUNDLES bit in ofp_capabilities to indicate switch support for
bundles.
* Bundle Features MP message not supported
* No support for scheduled bundles
* ONF Experimenter messages 2300 (ONF_ET_BUNDLE_CONTROL) and 2301
(ONF_ET_BUNDLE_ADD_MESSAGE) instead of standard OFP messages 33
(OFP_BUNDLE_CONTROL) and 34 (OFP_ BUNDLE_ADD_MESSAGE).
Other than that the message syntax and semantics seem identical
* ONF experimenter error codes for bundles errors in the range 2300-2315
instead of standard error codes 0-15 for error type OFPET_BUNDLE_FAILED.
Otherwise same meaning.
Inside OVS it seems that standard OF 1.5 and OF 1.3 extension messages are
internally mapped to a common message type. Errors are mapped back to standard
OFP error (type, code) for OF 1.5 and experimenter error type in OF 1.3.
So, the OVS bundle implementation for OF 1.3 should be faithful to EXT-230.
BR, Jan

Subject: OVS - ODL Sync on OF Bundle in 1.3
When: Monday, 23 January, 2017 17:00-18:00 (UTC+01:00) Amsterdam, Berlin,
Bern, Rome, Stockholm, Vienna.
Where: Skype Meeting
Hi Jarno,
OpenDaylight folks are finally starting to implement support of OpenFlow
bundles as a basis for the bundle-based hitless recync procedure we discussed
earlier. As ODL does not yet have protocol support for OpenFlow versions 1.4 or
1.5, they intend to implement the bundle extension to OF 1.3 as specified in
EXT-230 in
https://www.opennetworking.org/images/stories/downloads/sdn-resources/onf-specifications/openflow/openflow-extensions-1.3.x-pack2.zip
Would you have time for a short meeting on early Monday to discuss and
confirm whether the OVS implementation of bundles in OF 1.3 is compliant with
EXT-230 and has everything they need?
Thanks, Jan
